A president of the supreme court, in Ulm, named Pfizer, attests the truth of the following case: A gentleman, holding an official situation, had a son at Göttingen, who wrote home to his father, requesting him to send him, without delay, a certain book, which he required to aid him in preparing a dissertation he was engaged in. The father answered that he had sought but could not find the work in question. Shortly afterward, the latter had been taking a book from his shelves, when, on turning round, he beheld, to his amazement, his son just in the act of stretching up his hand toward one on a high shelf in another part of the room. “Hallo!” he exclaimed, supposing it to be the young man himself, but the figure disappeared; and, on examining the shelf, the father found there the book that was required, which he immediately forwarded to Göttingen; but before it could arrive there, he received a letter from his son, describing the exact spot where it was to be found. A case of what is called spectral illusion is mentioned by Dr. Paterson, which appears to me to belong to the class of phenomena I am treating of. One Sunday evening, Miss N—— was left at home, the sole inmate of the house, not being permitted to accompany her family to church on account of her delicate state of health. Her father was an infirm old man, who seldom went from home, and she was not aware whether, on this occasion, he had gone out with the rest or not. By-and-by, there came on a severe storm of thunder, lightning, and rain, and Miss N—— is described as becoming very uneasy about her father. Under the influence of this feeling, Dr. Paterson says she went into the back room, where he usually sat, and there saw him in his arm-chair. Not doubting but it was himself, she advanced and laid her hand upon his shoulder, but her hand encountered vacancy; and, alarmed, she retired. As she quitted the room, however, she looked back, and there still sat the figure. Not being a believer in what is called the “supernatural,” Miss N—— resolved to overcome her apprehensions, and return into the room, which she did, and saw the figure as before. For the space of fully half an hour she went in and out of the room in this manner, before it disappeared. She did not see it vanish, but the fifth time she returned, it was gone.
